Some signals on the beam monitor, seems they are optimising it.
System Check OK |

Gleb Vorobyev tried for few hours to fix the ion source but without success.
So, there will be no beam in CRYRING during this night shift. Today at about 08:00 the efforts to fix the ion source will be restarted. |

Beam is still beeing tuned. Target is off.
- Motor on manual |

UPDATE: THE PROBLEM IS SOLVED FOR NOW:
Doing the calib for the 5th time eventually worked.

08:00 Woke up to message from Carlo explaining the server had crashed.
Anydesked into the machine.
Merger was showing just data transfer it was not showing Transfer => Merger

Thu Feb 24 05:09:47 2022, CB, PE, EM, Inlet valve at target closed + problems with turbopump
|
The turbo pump E1 is continuing to draw too much current and the rotation frequency has steadily decreased from 817 Hz at the beginning of the night
shift to 800 Hz now. The frequency recovered after the temperature was increased.
Both of the valves (inlet and dump) have been closed to improve the vacuum in the ring. |

Thu Feb 24 04:17:35 2022, CB, TD (remotely), MIDAS DAQ no longer working

DAQ server crashed around 24:00
Rebooted server but could not could not rescue remotely - could not contact raspberry pi in control of FEE bias.
Entered cave, rebooted raspberry pi. Would not accept remote connections. |
